Use the --minarea option to mri_surfcluster (not the CSD).

Hi list, please, could you help me because from several days I'm trying to have a solution.I have performed a seed-based fcMRI analysis by FAST. After mri_glmfit, I have obtained a sig.nii.gz which contains uncorrected results.I have corrected by FDR using the graphical interface provided in tksurfur. The FDR corrected contains some very small areas (<5-10 voxels) which I would like to hide in order to present a more clear map. How is possible to do it?I have tried with mri_surfcluster. To have vwsig.nii.gz I should have a CSD file. But this file could be also produced when FDR correction is applied? I'm very confused. Thank you very much for your work. Kind regards. Stefano

just use the FDR thresholded input and set --thmin to 0.5
